ABSTRACT:
An apparatus (such as a valve assembly or other actuator) includes a pressure plate having a first hole and a second hole. The apparatus also includes a plunger configured to selectively cover the second hole of the pressure plate. The apparatus further includes a coil configured to move the plunger away from the pressure plate to uncover the second hole of the pressure plate in order to allow a material to flow through the apparatus. The coil is also configured to move the plunger towards the pressure plate to cover the second hole of the pressure plate in order to block the material from flowing through the apparatus. Pressure may equalize on a first side and a second side of the pressure plate after the plunger covers the second hole of the pressure plate.
